In contrast to typical segment LCD driver solutions today, the highly reliable NXP PCF8576D LCD driver supports a wide LCD supply range from 2.5 V to 6.5 V, making the LPC11D00 and LPC12D00 an ideal choice for interfacing with both low-threshold and high-threshold LCDs. The integrated PCF8576D increases system reliability and quality, and reduces electrical interconnect and compatibility issues, while incorporating key features such as on-chip display RAM and versatile blinking modes. In addition to blinking the whole display, the LPC11D00 and LPC12D00 also support alternate messages to be displayed at a configurable blink frequency on an arbitrary selection of LCD elements. Display data sent from microcontroller can be stored in the 40 x 4-bit on-chip display RAM which supports a direct mapping to the LCD elements on the display. Furthermore, these features can be maintained while the microcontroller is in low-power mode, making the LPC11D00 and LPC12D00 a competitive solution for low-power 8/16-bit applications that require low-cost segment LCD integration.
The LPC11D00 supports up to 32 KB of Flash, 8 KB of SRAM and offers a rich peripheral set, including 2 SSPs, I2C (FM+), UART, 4 system timers and a 8-channel high-precision 10-bit ADC. As an extension of the energy-efficient LPC1100L family, the LPC11D00 also features unique API-driven power profiles providing users with ready-to-use power management templates allowing designers to do runtime optimization of performance, efficiency and active power consumption with simple API calls.
The LPC12D00 extends the feature set of the LPC11D00 with up to 128 KB of Flash and highly innovative analog peripherals such as dual analog comparators with 32 levels of voltage reference, edge and level detection, and output feedback loop. As the newest addition to the LPC1200 Industrial Control Series, the LPC12D00 is a highly reliable solution for safety-critical industrial automation and white goods applications. The LPC1200 family is rated as high immunity, based on the Electrical Fast Transient (EFT) test conducted by Langer EMV-Technik GmbH per IEC61697-1 recommendations and is IEC 60730 Class B-certified.
The NXP LPC11D14 and LPC12D27 microcontrollers are currently sampling and will be available from distributors worldwide in Q4 2011 in 32-KB and 128-KB Flash sizes. Recommended distribution unit pricing for 10,000 piece quantities is US $1.53 for the LPC11D14FBD100/302 and $2.19 for the LPC12D27FB100.
